OIL-BURNER WICK.

Specification of Letters Patent.

)Eatented May '7, 1907.

Application filed June 12, 1.906. Serial No. 321,403.

ilo LU whom '/ri may concern/.-

Be it known that I, CoRonoN S. CANNON, a citizen of the United States,residing at Chicago, in the county oi Cook and State of Illinois, haveinvented a new and useful Oil- Burner licl, ot which the following is aspecification This invention relates to wiclr structures, and is moreparticularly intended for use in burners et the character disclosed inco-pen ding application, Serial No. 321,401, though perhaps features elthe present invention are useful in other relations. As set forth insaid application, the burner is of a type wherein the hydrocarbon isvaporized prior to its being burned, and a wick is employed forconveyingl the oil from the reservoir orfont to the place o'lvaporization.

One of the principal objects in the present invention is to provide awick for a structure oi the above character, that is not liable to beconsumed during operation, is readily adjustable to secure the highestdegree oit elliciency, and may be employed in igniting and e'tl'ecting apreliminary heating of the burner.

Another object is to provide a novel structure that will properlycooperate with the other parts oi" the burner in order to avoid wear andderangement of the wick.

In the accompanying drawings z-Figure l is a side elevation ot -a wicktube having the improved wick structure therein. Fig. 2 is a verticalsectional view through the same. Fig. 3 is a top plan view. Fig. 4 is across sectional view on the line 4&4 oi Fig. 2. Fig. 5 is averticalsectional view on the line 5 5- oi Fig. 2. Fig. 6 is a detailperspective view of one oi the plug wicks.

Similar reference numerals designate corresponding parts in all thefigures el the drawings.

In the embodiment illustrated, a wick tube 7 is in the 'term of an openended tube, and is oblong in cross section, the opposite side wallsbeing transversely bent throughout their length so that the oppositeportions ot said wiel: tulie are located at an obtuse angle, to eachother, as clearly shown in Figs. 3 and 4.

A v1 nain wick is employed, which. prelerab ly is composed o'l flatsections 8, formed of tabric, or other suitable absorbent material, andarranged against each other. Secured to one side orrl the body andprojecting above the same is a periorate plate 9 that also extends abovethe upper edge of the wick tube 7, and constitutes means, whereby thewick may be raised and lowered. The upper portion of the bodyfurthermore contains an incombustib'le section, preferably formed of asheet of asbestos that is doubled to provide separate leaves 10. Thisincombustible section is located between the upper portions oi.' thebody sections 8, and projects above the same, as shown. A periorateshaping platel 1 is arranged Vbetween the leaves of the incombustiblesection, and is thus embedded in the same, and in. the upper portion ofthe body. The various parts may be secured together by any suitablemeans, as for instance, a iastener 12.

rIhe main wick is of less width than the wick tube, and the upperportions ot the spaces thus lett are filled with plug wicks 13 that areinterposed between the edges of the wick, and the edge walls of thewick. tule. These plug wicks have metallic caps 14 comprising stripsthat extend over the tops of the plugs, and have depending terminal portions l5, the lower ends of which are bent inwardly, as shown at 16, andare embedded in the material oi the plug wicks. Said plug wicks`furthermore have depending legs 17, comprising metallic strips, theupper ends of which are fastened, as shown at 1S to the lower ends ofthe plug wicks, the lower ends of said legs being located in the bottomet the wick tube.

In actual practice, the upper ends oi' the body sections 8 do notproject above the upper edge of the wick tube and may be disposed belowthe same. The projecting portion of the incombustible section, however,preferably projects above the wick tube, and constitutes means, whichmay be ignited in starting the burner. The eil, carried by capillaryattraction to the top of the body, will, duringits passage, be heated inthe tube by the llame, and thus be vaporized. Inasmuch, however, as theupper ends of the body sections 8 are disposed at or below the top olthe tube, the llame will not come into contact therewith, and there isseldom danger el burning. Of course in time, the structure becomesscorched and wasted a trii'le on top, but trimming is seldom needed.However, when it becomes necessary to rearrange the wick, the same willbe raised out of the tube by means of the plate 9, and if necessary,additional sections may be added to the lower end. The metallic plate,cmbedded in the upper portion of the wick serves to maintain its shape,and prevents IOO buckling of the wick so that it will at all times beproperly shaped to the wick tube. The plug wicks serve to close theupper ends of the spaces between the wick and the edge walls.

From the foregoing, it is thought that the construction, operation, andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction, may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a wick structure, the combination with an absorbent body, of anabsorbent incombustible section having its lower` portion. embeddedtherein and its upper portion projecting above the body, a metallicshaping strip embedded in the section and terminating short of the topof the body, and securing means passing through the body, the lowerportion of the section and the strip.

2. In a wick structure, the combination with an absorbent bodycomprising sections, of an absorbent incombustible section having itslower portion located between the body sections and its upper portionprojecting above the body, and a perforate metallic shaping stripembedded in the incombustible section and terminating short of the topof the body.

3. In a wick structure, the combination with an absorbent bodycomprising sections, of an absorbent incombustible section coinprising adoubled sheet having its end edges projecting above the body and itsdoubled end located between and in contact with the body sections.

4. In a wick structure, the combination with an absorbent bodycomprising sections, of -an absorbent incombjustible section comprisinga doubled sheet having its end edges projecting above the body and itsdoubled end located between and in contact with the body sections, and aperforate metallic shaping strip located in the incombustible sectionand terminating short of its upper end.

5. In a wick structure, the combination with a wick tube, oblong incross section and having a single opening therethrough, of a main wicklocated in the opening and extending across the same but terminatingshort of one of the walls of said tube, a separate plug wick arranged inthe opening and filling the space between the said wall and the mainwick, said plug vwick terminating short of the lower end of the wicktube, and means connected to the plug wick and depending within the tubefor supporting said plug wick in the upper portion of said tube.

6. In a wick structure, the combination f with a wick tube, of a mainwick located therein, and a separate plug wick arranged in the tube atone edge of the main wick, said plug wick having a metallic cap.

7. In a wick structure, the combination with a wick tube, of a main wicklocated therein, a plug wick located along side the main wick, and adepending metallic leg secured to the plug wick and extending downwardlyinto the tube alongside the main wick.

8. In a wick structure, the combination with a wick tube, ol' a .mainwick located therein and terminating short of the opposite edge walls ofthe tube, plug wicks arranged between the upper portion of the y mainwick and the edge walls, said plug wick terminating short of the lowerend of the main wick, metallic caps covering the plug wicks, anddepending metallic legs carried by the plug wicks and depending belowthe same between the main wick and the edge walls of the tube.

9. In a wick structure, the combination with a wick tube, transverselybent throughout its length, of a main wick located in the tube andterminating short of certain of the edge walls thereof, said main wickcomprising absorbent body sections, an incombustible section locatedbetween the upper portions of the absorbent sections and projectingabove the same, a shaping plate embedded in the incombustible section,plug wicks located at the opposite sides of the main wick and arrangedin the Vwick tube, metallic caps for the plug wicks, and depending legscarried by the plug wicks and extending downwardly alongside the mainwick.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
